a citizen of the United States, and .a resident of Bowling Green, in the county of Wood and State of Ohio,have made an InventionAppertaining to lVashing Machines and I do hereby declare'the following to be a full, clear, and exact description of the invention, such 'aswill enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the characters of reference marked thereon, which form a part'of this specification.

This invention relates to washing machines, and particularly to those of the swinging tub type as distinguished from washing machines of therotary tub and oscillating dolly types. V "The primary object of the invention is the provision of a washingemachine having a clothes container or basket mounted for rocking movements withinthe tub thereof and having mechanism operable to impart predetermined" opposed rocking movements to the tub and container, whereby the washing liquid within the tub is forced with greater velocity and cleaning effect through the container. and clothes therein than would be the case if either-the tub or container alone were rocked. i

Further objects and advantages of the invention will be apparent from the following detailed description thereof.

While the invention, in itsbroader aspect, is capable of embodiment in numerous forms, a preferred embodiment thereof is illustrated in theaccompanying drawings, inwhich,- 1

Figure 1 is an end elevation of a machine, embodying the invention, with parts broken away. Fig. 2 is a fragmentary do tail of one of the basket carrying arms" and its supporting member taken on the line 2 2 inFig. 1. Fig. 3 is a side elevation of the machine, with parts broken away, and Fig. 4Cis acdiagrammatical view illustrating the relative movements of the tub and basket.

Referring ,to the drawings,;1 designates a frame of rectangular skeleton form having a beam member 2mounted on the top thereof; along each of its frontand rear edges. The frame also has a stationary upright member 3 at each side thereof centrally of its ends. i i

BOWLING GREEN, OHIO MACHINE.

1921. Seria1 No. 474,910.

The tub 4 of the machine is suspended for rocking movements lengthwise of the frame by two sets of rocker-arms 5,. which are ivotally suspended from bearings 6 securec to the ends of the respective members 2 and resting on the top side bars of the frame. The lower end of each rocker-arm 5 has a pin or stud 7 projecting inward therefrom under a respective hooked bearing lug 8 on the adjacent tub end. It is evident that the ends of the tub project freely between the suspending arms of the respective pairs and that the tub is suspended by the arms in a manner to permit free horizontal swinging movements of the tub lengthwise of the frame. The ends of the tub are vertically rounded in convex form with respect to the tub center and the tub isv provided. with a large opening in its top but which is restricted with respect .to the ends of the tub. The tub may be lowered from the rockerarms and removed from the frame by merely swinging the rocker-arms and their studs 7 out from engagement with the hooks 8. i

The clothes container or basket 9 is provided with impervious sheet metal sides and has its bottom and ends formed of any suitable pervious material, such,for instance, as wire mesh, to permit a free circulation of the washing liquid therethrough. 'The container is open at its top, in the present instance, between the two top cross-bars 10, which connect the sides and act as bracing means therefor. While the container may be of various shapes it is preferable to verti cally round the ends thereof and to have the bottom drawn upward at its center to form a transverseinverted V-shaped ridge within the basket. A cross reinforcing bar 11 is provided at the apex portion ofthe bottom. The container 9 is pivotally suspended for vertical rocking movements by a pair of arms 12, which are rigid with respect to the frame and project down into the tub i near opposite sides thereof from the respective members 2 to which the arms are rigidly secured, as best shown in Fig. 2. Thelower ends of the arms 12- are provided with bayonet slots 13 for releasably receiving bearing studs 14 projecting from the respectivesides of the container 9, such studs being located at approximately the center of the container sides.

An upright lever 15 is disposed at the inner side of each upright frame bar 3, be-

ing pivoted thereto at 16, which pivot, in

the presentinstance, is located below'the rocking ivot of the container 9. The upper end of the lever extends above the frame and is provided with a handle 17 to facilitate a hand rocking of either lever. The handle 17 in the present instance is carried by an inverted U-shaped .member; 18 which has one leg provided witha vertical slot 19-folpivotally and adjustably straddling a pivot stud 20 on the respective lever, and has its other end extending down within the tub 4 at the respective outer side of the container 9 and fixedly connected to the container side at a point above its rocking pivot 14, as.at.21. It is thus evident that upon a rocking of the lever 15, which, really includes as a part thereof the member 18, the container will be caused to rock on its rocking axis. I i r In order that a rocking of the levers 15 may also impart swinging movements to the tub lthetub suspending arms 5 of one pair are connected to the respective levers 15 by links 22, which are in pivotal connection at their ends with the arms and lever connected thereby. It is clear by reference to Fig. 1 that when the .upper ends of the levers 15 are rocked to the left from the full line position-the tub will be swungto the left to the dotted line position,and" that the container 9 will at thesame time be rocked upward at the right fromthe heavy dotted line positionto the light dotted line position, thus causing opposed movements of the tub and basket, which is evidenced by the fact that the right hand end of the container during suchmovement swings up toward the approaching right-hand end of thetub. This action causes a -restriction of the spaces be tweenthe tub and container at first one end and then the other thereof as the rocking continues and a consequent forcing of the water by the tub ends, first in one direction and then another through the container lengthwise thereof, the force of movement of the water being considerably greater than would bethe case if either thetub or container alone hadmovement. v

To provide a poweroperatingmeans for the levers 15 a motor 23 is mounted on the bottom portion of the frame at one end thereof and connected by a belt 245 to apulley 25 mounted, in the present instance, on a shaft 26 with afly wheel 27. a This shaft is journaled in a bearing28 and has a worm 29. inmesh with a worm-wheel 30 on a shaft 31 journaled in the bearing 28 and extend,- ing crosswise of the frame. This shaft carries; a clutch controlled crank-wheel 32, the crank-lpin"33 of which is connected by a zpitman 34; to a cross rod 35 connecting the lower ends of the two levers 15 at a point below the tub. It .is thus evident that a turning of the crank-wheel 32 will impart predetermined rocking movements to the levers. y

I wish it understood that my invention is not limited toany specific construction, arrangement or formof the parts, as it is capable of numerous .modifications and changes without departing from the spirit of the claims.

Having thus described my invention, what I claim as new and desireto secure by Letters Patent, is,'- I v 1.
